I don't think its impossible. as a matter of fact it could be done quit easely. Pick what area you want to be out lined, and make those dimonds a little smaler and add a very narrow trim around them, make sure after you put your trim around make sure same size as other blocks, and be careful on the placement. but it can be done. God bless. Penny...PS I would separate the star highlights a little so you could see the stars very clear, like every other.
